Electrical current flows easily through a conductor, but does not flow through an insulator. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

For example, in so-called Mott insulators, the electrons ought to flow freely and the materials should therefore be able to conduct electricity as well as metals.

Ohm’s law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the ...

In general, system construction requires cables to be supported. In our case, the supporting devices for the covered conductor are spacers and insulators. When a polyethylene covered cable comes in ...

According to researchers at the University of Cambridge, electrons are largely stuck in one place in an insulator, whereas in a conductor they flow freely. But their findings of the behaviour of the ...
